i got my boat in nov and for our first run this year we used the gas that was left over from purchasing the boat. after my first time out i tried to top the boat off and after about 2/3 of a gallon it started to spit back at me. i tried to just barely pump anything in at a slow speed and it kept spitting back at me. i had enough gas in the boat to go out again and now there is pretty much half a tank left in the boat. i tried to fill it up again and the same thing happened. so today i tried to use a gas can at home to do it as slow as possible and after about half a gallon it wouldnt take anymore...i let it sit for a few minutes and went back to check on it and it was still sitting right at the gas can. i left and came back about 2 hours later and the same amount of gas was still there. im not sure what the problem is?

i blew into the vent right next to the gas tank and i saw the gas that was sitting in it begin to move so im not sure if that means that the vent is clear or not? any advice would help!

it runs behind the dash/kick panel, into the ski locker then along tht top of the ski locker to the gas tank. sounds like you may need to pull the floor and kick panel out and see if you have a kinked line

I've pulled the floor panel and examined the lines in the ski locker. There doesn't appear to be any kinks in the sections of the lines that are accessible via the locker, so I guess next step is to pull the dash panel off.

Yea, I was just thinking that maybe a fat sac was pushing on a fill hose inside the boat, kinking it to the point that your having problems filling it. I'm sure a kinked vent line would do it to some degree too, but not to the degree that your describing.

crazy. neither one was blocked, turns out the fill line just dipped downward and then upward near the hull, and couldn't make it "up the hill" in the hose at the upward section. I bent the line a bit by hand, and sure enough, the gas all emptied into the tank.
